Cloud Migration Roadmap: Apply the Six Rs With Business Context

The job the system must support

Cloud migration should improve a defined constraint—resilience, change speed, scale, security, or cost—while controlling application, data, identity, and operating risk. This playbook is for technology leaders planning workload migration from servers, hosting providers, or another cloud. Its practical goal is which workloads to retain, retire, rehost, replatform, repurchase, or refactor and in what order without moving hidden work into spreadsheets, inboxes, or an unmanaged support queue.

Follow a real case through the organization before drawing the future workflow. Record every handoff, wait, duplicate entry, exception, approval, evidence request, and correction. Ask frontline users what they do when the documented process fails; those workarounds reveal the requirements most likely to be missed.

Choose the level of change

Rehost to reduce immediate infrastructure risk

Use this when one repeated bottleneck has a clear owner and can be improved without reorganizing the whole operation.

Replatform for managed operations

Use this when the customer or employee outcome crosses systems and team boundaries, making local automation insufficient.

Refactor selected high-value capabilities

Use this when several workflows share identity, rules, evidence, integrations, and reporting, and the organization is ready to own a platform.

Standard operating model

• Control 1: Inventory workloads, dependencies, data, traffic, service levels, licences, and owners.
• Control 2: Define target outcomes and choose a migration treatment per workload.
• Control 3: Establish landing-zone identity, network, logging, policy, secrets, backup, and cost controls.
• Control 4: Migrate a representative low-blast-radius workload and refine the runbook.
• Control 5: Rehearse data cutover, validate operations, decommission safely, and review realized outcomes.

Every automated path needs an exception path with a named queue, severity, owner, service level, supporting evidence, and allowed corrective actions. Operators should never need database access to recover ordinary business failures.

Roles and controls

• A business owner defines policy, acceptable exceptions, and the outcome.
• Frontline users validate whether the design reduces effort in the real environment.
• Product and engineering own workflow state, usability, integrations, and telemetry.
• Security, privacy, finance, or clinical owners approve controls relevant to the domain.
• Support owns detection, communication, escalation, and documented correction.

What can break

1. Lift-and-shift can preserve poor reliability while increasing variable cost. Test this in a scenario review and keep the recovery evidence.
2. Unknown dependencies appear during cutover if traffic and job flows were not observed. Test this in a scenario review and keep the recovery evidence.
3. Keeping duplicate infrastructure after launch erodes the expected business case. Test this in a scenario review and keep the recovery evidence.

Daily, weekly, and monthly review

Daily: inspect failed, blocked, or aging work and confirm customer-impacting exceptions have owners.
Weekly: review the leading workflow measures, top exception causes, support feedback, and changes released.
Monthly: compare business outcomes with the baseline, confirm access and policy, and decide which root cause deserves the next investment.

The scorecard should stay close to the workflow:

• Migration success, rollback, and service-interruption rates.
• Release lead time and infrastructure change failure rate.
• Availability, recovery performance, and security control coverage.
• Unit cost per transaction, customer, or workload.

FAQ for operating teams

Should every workload move to the cloud?

No. Retain or retire systems when migration does not improve the constraint enough to justify risk and cost. Hybrid arrangements can be deliberate.

What should migrate first?

Choose a workload that exercises the target operating model but has limited business blast radius and well-understood dependencies.

How do we prevent cloud cost surprises?

Tag ownership, set budgets and anomaly alerts, size from observed demand, review managed-service pricing, and track cost against a business unit.
